Product Description
The FX2N‑16EX is a 16‑point digital input extension module for MELSEC‑F (FX) series PLCs, providing 24 VDC input capability to expand system I/O density on FX2N architectures. Inputs are photocoupler‑isolated with clear LED indication per channel, supporting no‑voltage contact and NPN open‑collector signal formats. Typical sensitivity is 3.5 mA or more ON and 1.5 mA or less OFF, with approximately 10 ms response, making it suitable for general industrial signal interfacing. The unit uses a vertical terminal block (M3 screw) for field wiring and derives internal power from the host sequencer. Electrical characteristics include 4.3 kΩ input impedance and nominal 5 mA at 24 VDC input current, with allowable input voltage of 24 VDC ±10%. Designed for reliable operation, the module features photocoupler insulation and standard environmental and noise immunity attributes found in FX2N accessories. It is intended for DIN‑rail mounted FX systems where compact digital input expansion is required.
